High on the western side of a col between the Comeragh Mountains and a neighbouring hill, a ringfort sits in the middle of a coniferous plantation, its earthworks left unplanted while the timber crop has grown and been felled and replanted around it. That small exemption matters: the monument survives largely intact, and the contrast between the managed forestry and the ancient, untouched enclosure gives the site an oddly suspended quality, as though the trees have simply agreed to work around it.

Ringforts, sometimes called raths, are the most numerous monument type in the Irish countryside, the enclosed farmsteads of early medieval farmers, typically dating from roughly the fifth to the twelfth centuries. Most consist of a circular or subcircular area defined by an earthen bank and an outer fosse, the ditch dug to provide the material for the bank. This example at Curraghkiely follows that pattern closely but preserves its detail well. The enclosure is nearly circular, measuring about 23 metres east to west and 20.5 metres north to south, with the interior dimensions somewhat smaller at around 18 by 16 metres. The surrounding bank is substantial, between seven and eight metres wide, and the fosse outside it is separated from the bank in places by a distinct flat berm, a narrow level shelf of ground that sometimes indicates a carefully constructed rather than simply functional design. On the southern, upslope side, the bank rises to around 2.5 metres on the interior face and 2.7 metres on the exterior; the northern, downslope side is considerably lower, which is typical where the natural gradient does part of the defensive work. The entrance, only 1.2 metres wide, sits at the north-north-east, approached by a causeway of similar width crossing the fosse. A second rath lies roughly 140 metres to the north-east, suggesting this was once a small cluster of enclosed settlements rather than an isolated farmstead.
